Interaction of haemoglobin with ions binding of inositol hexaphosphate to human haemoglobin a

The interaction of inositol hexaphosphate with methaemoglobin.

1. Inositol hexaphosphate causes the shape of the oxidation-reduction equilibrium curve to become hyberbolic at acid pH values. 2. Inositol hexaphosphate also causes a decrease in the alkaline oxidation Bohr effect at these same pH values. 3. These results support the idea that inositol hexaphosphate causes methaemoglobin to take up the deoxyhaemoglobin quaternary structure at pH6.5.

Haemoglobin Binding with Haptoglobin UNEQUIVOCAL DEMONSTRATION THAT THE f-CHAINS OF HUMAN HAEMOGLOBIN

Haptoglobin binding to haemoglobin and its isolated a and #-chains was studied by use of a highly sensitive solid-phase radiometric assay. As expected, adsorbents of haemoglobin bound '25I-labelled haptoglobin more efficiently than did adsorbents of the (achain. However, unexpectedly, adsorbents of the f-chain were found to be essentially identical with those of the a-chain in their ability to ...

Binding of oestrogens to human erythrocytes and haemoglobin.

Oxygen-linked binding of halothane to human adult haemoglobin.

The affinity for oxygen of normal human haemoglobin (Hb) solutions was measured in the presence of increasing concentrations of halothane. We observed a maximum increase in P50 of 25% with halothane 40 kPa compared with control (oxygen-argon gas mixtures) indicating the oxygen-linked character of the binding of halothane to the Hb molecule. The effect of halothane on P50 was independent of pH b...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
